' n' Losantos-jenn invention relates to new and use-ful improvements ingasolene trucks and more particularly to a-'truck adapted for use in 1 'connection with the logging industry and the primary object of the invention is to provideva simple and ecient device oft-his character which is adapted to supersede the devices now in use for conveying logs from place toplace.

A further object of the invention resides Vin providing a pair of trucks, one of which is provided with a rigid and the other with arocking 'bolster adapted to support the 1o thereon, and a still further object resi es in the lprovision of a device'which is extremely simple and durable in construction, inexpensive to manufacture and Aone which will be very ellcient and useful in operation.

With these and other objects in view, the invention consists in the novel features ofy construction, combination and arrangement of parts as will be hereinafter referred to l and' more particularly pointed` outin the specificationand claims. v In the accompanying drawing forming -a part of this application, Figure 1 is a side elevationl of, the device with parts thereof broken away; and Fig. 2 is a plan view thereof with parts broken away. j 1

In describing my invention, I shall refer to t hedrawingin which similar reference cljaracters Vdesignate corresponding parts thfolghoutthe several?, views and in which '11 and 2 indicate frames rigidly supported on the trucks 4, said frames-being connected Ytogether b means of' a central longitudinal beam 4 w ich is pivotally connected -tot-he frame 1, at the point 9 andl is rigidlyjen- Y gaged with the frame 2. Suitably mounted on the frame 1 is a gasolene engine 3 of any -desired horsepower and extending longitudinally ofthe frame 1, is the drive shaft 3', said drive shaft having the reversible i Specitlcation of Letters Patent.

which is readily operable by means of the lever 5. The rear end-of the drive shaft 3 has the beveled gear 6 mounted thereon i "clutch 5 mounted 5in' the length thereof which meshes with a similar gear 7 carried on a transverse shaft 7. This transverse shaft '7 is disposed just forward of the rear wheels of the truck 4 and has mounted on lthe ends thereof the pinions 8 which are mashed with the gears 8 mounted inconnection with the inner faces 0f the last menl tioned wheels. From this construction it will be seen that. as the engine 3 is operated,

the rear wheels of the truck carrying the' frame 1 will becaused to rotate in either one direction or the other,'as the case may be, thereby driving the device on the rails 9 Pivotally mounted at the point 12, onthe yrear portion of the frame 1 isa rocking bolster 10, while an additional bolster 11 is rigidly mounted on the'frame,2. These bolsters 10 and 11 -are adapted. to directly receive the `logs v12 thereon and thus the movement of the forward frame with respect to the rear frame will be compensated for. In this connection, it mustv be also stated that a pony truck 13 ispivotally mounted on the frame l at the forward end thereof through the medium of the kingbolt 13. As thel engine transmission is mounted in connection with a truck which isrigidly mounted on the frame 1, however,

it will be seen that the various parts thereofv cannot vibrate without the complete frame and truck vibrating therewith.

From the, foregoing description of the construction of my improved device, the operation thereof will be readily understood and it will be seen that I have provided a simple inexpensive, and efficient means for.

carrying out the objects of the invention.

While I have particularly described the' elements best adapted to perform the functions set forth, it is obvious that various changes in form, proportion and in the minor .details 0f vconstruction may be resorted to without departing from the spirit or sacrificing any of the principles of t-he invention.

Having thus described4 this-invention,

what I claim 1s A device of the classdescribed comprising a pair of frame sections respectively mounted on trucks, a central beam mounted on the upper face of the la'st :mentioned on one oi said' trucks and extending beyond truck adjacent the rear end .of the'latter. 1o
